Abstract

La présente invention se rapporte à un écran du type à pression tactile complexe ajoutée (100), qui permet à un écran tactile capacitif de détecter une pression de type résistif. L'invention se rapporte d'autre part à un procédé d'activation par pression utilisant ledit écran. Une structure selon la présente invention comprend : une première partie de substrat (110) qui comprend un premier substrat transmissif (111), une première couche mince conductrice transparente (112) qui est appliquée par stratification sur le premier substrat transmissif (111), et des moyens de mise à la terre (150) qui sont connectés électriquement à la première couche mince conductrice transparente (112) ; une seconde partie de substrat (120) qui comprend un second substrat transmissif (121), et une seconde couche mince conductrice transparente (122) qui est appliquée par stratification sur le second substrat transmissif (121) ; et une couche d'isolation et d'espacement (130) qui comprend des entretoises qui sont placées entre la première partie de substrat (110) et la seconde partie de substrat (120) de sorte à espacer et à isoler la première partie de substrat (110) et la seconde partie de substrat (120) l'une par rapport à l'autre, les entretoises étant disposées selon une forme spécifique. Quand une pression externe est appliquée par un utilisateur depuis le côté supérieur de la première partie de substrat (110), un trajet électrique se forme à travers la première couche mince conductrice transparente (112), la seconde couche mince conductrice transparente (122) et les moyens de mise à la terre (150) par un court-circuit qui se produit entre la première couche mince conductrice transparente (112) et la seconde couche mince conductrice transparente (122) à l'endroit où la pression externe est appliquée. Par voie de conséquence, le schéma d'excitation selon la présente invention permet à un écran tactile capacitif de détecter des coordonnées d'une position touchée lorsque l'écran du type à pression tactile complexe ajoutée (100) est touché.
